Project 38 Plum jam

It is September and it is plum season. I made 9 jars of jam. One I shall give to our neighbour as a good part of the plums came from her tree.

I used 2 kg of jam and 1600 gr of sugar. I let the plums soak in the sugar overnight, then boiled it for some 15 minutes. I let it rest for one day to make sure the jam is thick enough. I then boil it again before poring in to the jars.
